Re: Potted Bamboo Hand Sectioned

Image stacking is common practice with macro photography.

A true macro lens has an inherently shallow depth field, and as such an object with any depth to it, may require a considerable number of images to be taken at different focus points

It can be very effective.

Re: Standard Plan Objectives v Plan Infinity objectives.

As always 'apo; you speak wise words based upon extensive experience. However, as I think I have said before, to me, micrcroscopy is not a serious hobby, but more fascinating pass time. wheres as my serious, and expensive interest is photography. I bought the Bresser Trino to see if microscopy was s...

Re: Microscope Upgrade

Hi Alan I have sold the Bresser, and have pretty much made up my mind, subject to getting the right answers back to the questions I have submitted to the supplier. Unfortunately, it won't be from Bresser, as their customer support has been excellent, but the model I wanted, the TRM301, is only avail...

Re: Standard Plan Objectives v Plan Infinity objectives.

Absolutely Alan, but not always practical, which is why I wouldn't buy second hand on e-bay, or from some distant private seller. At least when buying new i have some comeback if it is below the expected standard. The only two places to 'try before you buy' in the UK is GT Vision, and Brunel. GT are...

Re: Hello Microbe Hunters - New Here and Ready to Buy my Next Microscope

I looked at these low pixel population Micro Cams, and as a seasoned photographer, decided to go down the DSLR route. Not wanting to put my Full Frame EOS 5d MklV on a microscope, as it is both an expensive, and heavy 'beast', I bought a budget end EOS 4000d. Lightweight plastic body, and an 18mp AP...

Re: Hello Microbe Hunters - New Here and Ready to Buy my Next Microscope

Hi, and welcome aboard.

Whatever microscope you buy, as long as you enjoy using it, is what really matters.

BTW, I'm a relatively new to this group, and have to say I much prefer it to the Amateur Microscopy Facebook group, which comes across as being a bit elitist.

Re: Infinity corrected microscopes

I'm no expert Ivan, but I am led to believe that in terms of image sharpness, and resolution, there is no difference between infinity corrected optics, and 160mm RMS standard ones. However, again, as I am led believe, a microscope with infinity corrected optics is far more flexible when come to 'ref...

Re: Microscope Upgrade

I would hope that a Bresser microscope with Plan objectives, would have suitably matching eyepieces to go with it Bob.

I wasn't thinking about changing the achromat objectives on my existing scope for Plan ones, but a whole new microscope.

Re: Microscope Upgrade

Yeah, thanks for that Alan. :lol:

The TFM301 would be ideal Alan, as it is the same body as the TRM301, but with semi-plan objectives.

Unlike it more expensive brother, the TFM301 has LED lighting.

Now if Bresser could supply the TFM301 with Plan objectives, that would be the ideal solution.

I understand that infinity corrected objectives are more versatile when it comes to adding intermediate accessories, but if you want change any of the objectives, they have to be ones fr...

Although Paraffin wax has been a tried and trusted method of wax embedding for many years, it is a byproduct of oil refining in the production of Petroleum. As such it does contain harmful chemicals, that are released when burned (as in candles). It releases Toluene, and Benzene, both known Carcinog...
